Abstract

COPOLIAMIDAS SEMI-AROMATICAS Y COPOLIESTER-AMIDAS SON OBTENIDOS POR COLOCAR UNA POLIAMIDA ALIFATICA EN CONTACTO CON UN HIDROXIACIDO AROMATICO O AMINOACIDO, POR OPERAR A ALTA TEMPERATURA, BAJO CONDICIONES DE FUSION, POSIBLEMENTE EN LA PRESENCIA DE UN CATALIZADOR, CON UNA PROPORCION DE UNIDADES MONOMERO DE POLIAMIDA ALIFATICA A LOS MOLES DE HIDROXIACIDO AROMATICO O AMINOACIDO COMPRENDIDO DENTRO DEL RANGO DE DESDE 20:1 A 1:1. LAS COPOLIAMIDAS SEMIAROMATICAS Y COPOLIESTER-AMIDAS ASI OBTENIDOS PUEDEN MOSTRAR UN COMPORTAMIENTO DE CRISTAL LIQUIDO TERMOTROPICO PARA UNA FUNCION DE SU CONTENIDO DE UNIDADES AROMATICAS ENLAZADAS DENTRO DE LA CADENA MOLECULAR. SUS MODULOS ELASTICOS RESULTAN SER MEJORADOS RELATIVAMENTE A LAS POLIAMIDAS ALIFATICAS USADAS COMO EL PRODUCTO INICIADOR, Y LA ELONGACION A CAMBIO RESULTA SER DISMINUIDA. TALES POLIAMIDAS SEMIAROMATICAS Y COPOLIESTERAMIDAS PUEDEN ENCONTRAR APLICACION EN LA PRODUCCION DE ARTICULOS DE ALTA RIGIDEZ, POR MEDIO DE PROCESOS DE MOLDEO O EXTRUSION. PUEDEN TAMBIEN SER USADOS COMO MEZCLAS CON LOS POLIMEROS TERMOPLASTICOS USUALES, EN EL QUE ACTUAN COMO AGENTES REFORZADORES O COMPATIBILIZADORES.SEMI-AROMATIC COPOLYAMIDES AND COPOLIESTER-AMIDES ARE OBTAINED BY PLACING AN ALIPHATIC POLYAMIDE IN CONTACT WITH AN AROMATIC OR AMINO ACID HYDROXIACID, POSSIBLY IN A DEGREE CONDITION, IN A PRESIDENT FUSION CONDITION ALPHATIC POLYAMIDE TO THE AROMATIC HYDROXYCID OR AMINO ACID MOLES INCLUDED WITHIN THE RANGE FROM 20: 1 TO 1: 1. THE SEMI-AROMATIC COPOLIAMIDES AND COPOLIESTER-AMIDES SO OBTAINED MAY SHOW THERMOTROPIC LIQUID CRYSTAL BEHAVIOR FOR A FUNCTION OF ITS CONTENT OF LINKED AROMATIC UNITS WITHIN THE MOLECULAR CHAIN. ITS ELASTIC MODULES RESULT TO BE IMPROVED RELATIVELY TO THE ALIPHATIC POLYAMIDES USED AS THE INITIATOR PRODUCT, AND THE ELONGATION IN EXCHANGE RESULTS TO BE DECREASED. SUCH SEMIAROMATIC POLYAMIDES AND COPOLIESTERAMIDES MAY FIND APPLICATION IN THE PRODUCTION OF HIGH RIGIDITY ARTICLES, THROUGH MOLDING OR EXTRUSION PROCESSES. THEY MAY ALSO BE USED AS MIXTURES WITH USUAL THERMOPLASTIC POLYMERS, WHERE THEY ACT AS STRENGTHENING OR COMPATIBILIZING AGENTS.
